This invention relates to improvements in cross flow radiators, and hasfor its object .to provide a radiator and Ventilating apparatvus inwhich the air is uniformly heated and discharged into a room in' auniform temperature condition.

It is also an object of this invention toA provide, in connection with aVentilatingA and heating apparatus, means for creating a current of lairand directing the air from outside of the building to a point on theinside,

and then this air is discharged into the build-- `ing to allow it to beretarded in its forward movement and expand, and` after it has exphaving the tins arranged in a longitudinal position with relation to thecasing in which the fan element is located and suiiiciently lremovedfrom the fan element. the air can expand and that the amount of materialin 4the radiator may be materially reduced.

Under ordinary conditions a radiator six inches high would be necessaryif the tins run crosswise of the casing, but with the longitudinalarrangement and the expansion space radiator fins no higher than two anda half inches may be used, vand produce the sanie result as radiatorssix inches high would produce if the fins were crosswise of the casinginstead of longitudinal.

B y reducing the height of the radiator the total. height of the casingmayfbe reduced, thereby. enabling the whole unit to be used under lowerwindows than with higher heaters and larger casings.

YThese and other advantages will'appear from the following description,taken in connection with the drawings, in which there is shown avention. A

' Referring to the drawings:

Figure 1 is a vertical section on the line 1-1 of Figure 3.

Figure 2 is a view showing a part of the front of the casing. A

Figure 3 is a vertical section on the 3--3 of Figure 1. `Figure 4 is atop plan viewr of a radiator. Figure' 5 is a section on the line 5-5 ofFipure 4.

.Figuret is a section on the line 6 6 of preferred embodiment of thisinline Figure 5. panded, pass over heating tins by which ,the air isuniformly heated and tempered for t Figure 7 is-an end elevation of theradiaor. This air conditioning and air heating apparatus is inclosedwithin a casing 1. which has an inlet opening 2 for the admission offresh air into the interior of the casing. The admission of fresh airinto the casing is regulated b v means of a damper 3, as shown in Figure3. This damper may be arranged i to have automatic control or it may bemanuallv controlled. The damper control is no part of this invention.

The lower part of the casing is designated a chamber 4 into which cool.fresh air is admitted from the outside throughthe inlet 2. rihis chamberhas side walls'` as'shown in Figure 1` and has an outlet 6 through whichthe air passes from the chamber into a fan chamber 7. The fan chamber inthe present instance hasl two fans. Different numbers of fans mav heused. depending upon the size of the casing and the size of the fans.

Fan casings 8 are shown to be convolute in form with lateral openingstherein for the admission of air into the casing. These lateral openingsor inlets are indicated h v the numeral '9. ln the casing isa fan 10operated by a motor 11, which has a shaft 12 for operating the fans andto which the fans are attached. While the inlets to the fans arelaterally disposed-the outlets 13 lead upwardly into an expansionchamber, to be later described. The inlet part of the fan isfunnel-shaped so as to direct the air from the fan chamber into the. fancasings so that it may be delivered for heating purposes to theexpansion chamber.

'In each side of the main casing and attached to the walls thereof arebrackets 14, which have downwardly inclined parts 15 which tendto directthe incoming air into the fan .casings The part of each bracketimmediately above the inclined part is formed into a shoulder 16 forsupporting a plate 17 immediately above the exit or outlet from the fancasings. This plate has as many openings therein as there are fans inthe fan chamber, and adjacent each opening and to each side thereofthere is formed a turned-down flange 19 which projects into the outletpart of each fan casing and serves, in cooperation with the fan casings,to direct the air through openings 18 in the. plate.

vLocated in the openings 18 and immediately above the outlet from thefan casings are diagonally disposed deflectors 20. In the presentinstance four of these deleetors are shown in connection with each fan,and

of these four delectors two slant upwardly in one direction and theother two slant upwardly in another direction. By this means the airas'. it leaves the fans is divided into' all parts of the chamber.

This expansion chamber permits the air to expand and lose a part of itsvelocity so that as it reaches the radiator its motion is not so rapidand it has substantially a very broad cross sectional area of movementat -substantially a uniform speed for'all crosssections of the area. Theupper parts of the brackets 14 are formed into ledges 21 which-supportlegs 22, extending downwardly from a heater or radiator 23 whichhas at each end a right angular projection 23a. The legs 22, with thebrackets 14, form the expanv sion chamber 24, into which the air passesafter leaving the fans and in which it expands before entering theheater or radiator.

It will be noticed from the arrangement of the deflect-ors that the airis directed in currents longitudinally of the casing, and in order' thatthe radiator fins may have the greatest effect upon the air they arelikewise arranged longitudinally of the casing so that there is an equaldistribution 'of air through the length of the radiator.

The heater has an inlet 25 and an outlet 26' connected to theprojections for the admission and discharge of hot water or steam forheating purposes. Thenature of the radiator or heater is shown well inFigure 4. The radiator is composed of two casings or headers connectedby pipes or tubes 27.

I nto one of these casings the hot water or steam is admitted throughthe inlet, and from this casing it passes into the other casing throughthe pipes ,27, and .romtheother casing out through the dischargev `orloutlet 26. The two casmgs are also connected by a pipe 27a between oneend of one casing i casing is a cover,29 which has an outlet opening 30therein through which the airpasses from the main casing after passingthrough the heater and about the heating fins. This outlet may haveprovided therein louvers or means for controlling the current of airfrom the main casing into the room or building heated by the apparatus.
